The Human Brain

is a powerful processor which can analyze as well as execute.

We are Grey Sim

Derived from Grey-matter Simulation, Grey Sim is a leading player in the Edutainment (Education + Entertainment) sector in India. It is helmed and navigated by a group of enthusiastic, cross-disciplinary professionals who share a passion for grooming our next generation.

As enablers of dynamic activities that engage both the learner and the teacher, we work to create value for all stakeholders.

Our Mission

Our mission is to reach at least 1 million children in the next 3 years and bring about a positive change in their lives with our activity-based learning pedagogy, and thereby make them future ready.

What we do

All parents wish for only the very best for their children – including ‘the best education’. Most invariably fail to define ‘best education’. Given the fact that we cannot see the future and hence are quite unaware of what the ‘next big thing’ will be, it then becomes mandatory to focus on a willingness and ability to constantly learn.

At Grey Sim, we help kids become future-ready by simply ‘teaching them how to learn’, with a focus on bringing relevant and contemporary subjects to their attention. We strongly believe that our brain is not a mere pen drive to be used only to store data, but rather, is a powerful processor which can analyze as well as execute.

The Team

Our Brand Ambassador

Mike Senna

We are glad to introduce our brand ambassador, Mike Senna, known as the creator of live replica of #R2-D2, #Wall-E, #EVA and #BB8, and if you are fascinated to see these characters on screen, then you would surely love to see these characters in real life. Well it is easier said than done, but Mike has made it possible and if you are up for it and ready to join our Tinker community, then he would love to share some of his experience and latest projects. Working with Grey Sim in India. We are excited to get him connected with the budding makers community in India through our online portal. Who knows, we might get one of the great tinkers of present time.

Our Initiatives

We work towards Redefining the Learning by designing and executing educational programs for the children through various channels. We encourage Learning by Doing and to support this initiative we setup Tinkering Labs, which is an state-of-the-art facility, fully equipped with tools and equipment to give shape to young imagination and bring ideas to reality. With our proven experience of running STEAM(Science, Technology, Engineering, Arts and Maths) tinkering lab. We are already supporting 50+ schools across the country to establish Atal Tinkering Labs within their school to foster curiosity, creativity and imagination in young minds; and inculcate skills such as design mindset, computational thinking, adaptive learning, physical computing etc. For all the students who are associated with our tinkering labs, we provide them Monthly Impy box (DIY kit), delivered at their doorstep.

3D Learn

Today, one can see a rapid transition from 2 dimensional printing to 3 dimensional object printing. 3D Learn is an integrated yearlong Program which can extend any computer lab in school into a design and innovation lab equipped with G-bot, our indigenous 3D Printer. Students can actually produce a 3D model in a physical form, very easily and precisely. We have developed a state-of-the-art technology in the field of creativity and shaped it into a product which is capable of challenging the boundaries.

This is first time ever that such a high-end technology is reaching school students in India. We are proud to be associated with the young expert of this industry and are implementing this program for the prestigious schools in India.

Our program is designed to supplement mainstream school curriculum by providing an active learning experience through 3D models, educational kits and life experiences.
